:D any one have any plans/specs. for a home brew with gain, i built a 1/4 wave with
good swr , but no gain.???? :-? :-?

I am confused.

Are you building a dual bander with gain or two monobanders with gain?

Yes what do you want to do exactly a half wave at 70cm is only 13-14 inches so one could easily build a multi element Yagi for whatever gain factor you might wish to achieve. How about a nice Corner Reflector which is similar to a parabolic dish. Hmm what is the wavelength of satellite TV I thought I saw something on recycling them for either WI-FI or Ham usage... Time to google again...

omni directional like a hustler g6 ??? about 6 db :roll: :roll:

Check this one out 13 dbi

PS: There is a horizontal loop type, can't recall a proper name for it, that can get about 2dbi gain.

This one below is a full wave length long for HF usage, similar idea and 440 being in the 24 inch range makes such an antenna feasible...

Well, the hustler G6 is a colinear. I guess you can try to make one. I don't know how else you can get that much omni directional gain.

There is a 440 MHz repeater in SE Arizona that uses a (GET THIS!) a brazing rod as a TX antenna.....and it has quite good range for a 3W output repeater.

You can get those at Home Depot or Lowe's.... and brazing rod is a hard brass alloy which should be easy to solder and last a long time.

Or... buy a 6-pack of coat hangers and build a yagi. :lol:

Or have an abortion.

Oh wait. Never mind those are still legal.
